}Between 1.09b and 1.2b the timeout handling for bbnet was changed from a
}single 30 seconds timeout to three tries of 3, 5 and 12 seconds
}respectively.

}This means that if the service takes from 12 to 30 seconds before
}answering, then it would work with the old version, but won't with the
}new.

I'm not sure if that's it:
# time /local2/bb-1.09b/bin/bbnet mailhub:1109
0.013u 0.016s 0:03.14 0.6% 0+1k 0+0io 0pf+0w
# time /local2/bb-1.2b/bin/bbnet mailhub:1109
bbnet: TIMEOUT mailhub PORT 1109...
0.003u 0.018s 0:20.04 0.0% 0+2k 0+0io 0pf+0w

The old version comes back relatively quickly.

}Not knowing kpop, I can't tell exactly why the delay is so long, but for
}other services it's often a failing reverse dns lookup or a failing
}auth/ident request, either of which might take a timeout before the
}service responds.

It shouldn't be auth/ident requests, we don't do those, and dns is working
fine, forward and reverse lookups.  Does perhaps the newer version expect
something to be sent from the server where the old one didn't?  kpop doesn't
return its "+OK QPOP (version 2.53-krb-IV) at mailhub starting." until
after it's received sendauth() from the connecting side.
